SPECIFICATION forming part of Letters Patent No. 554,460, dated February 11, 1896.

Application filed July29, 1895. Serial No. 557,430. (No model.)

To ctZZ whom it may concern: Be it known that I, JOHN ROGGINGER, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, haveinvented certain new and useful Improvements in Cyclometers, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

In the manufacture of cyclometers, particularly of the kind more especially adapted for use in connection with bicycles, it is highly desirable that the construction shall be exceedingly light, durable and simple, in order to add as little weight as possible to the machine and withstand the jarring action incident to the travel of the machine. It is desirable also that the construction shall be such that the rider from his position upon the wheel can readily read the dials.

My invention has for its object to provide a light, simple, clieap, and durable construction of cyclometer, and this object has been accomplished by the novel features hereinafter described, illustrated in the accompanying drawings, and particularly defined in the.

claims at the end of this specification.

Figure 1 is a plan view of my improved cyclometer. Fig. 2 is a similar View from the opposite side. Fig. 3 is a view from the back or under side with the cover removed. Fig. 4 is a View in longitudinal section on line 4 4 of Fig. 7. Fig. 5 is a view in side elevation looking in the direction of the arrow, Fig. 1. Fig. 6 is a view, in side elevation from the opposite side of that shown in Fig. 5. Fig. 7 is a view in central vertical section upon an enlarged scale. Fig. 8 is a perspective of a spring-plate on one of the ratchet-wheel hubs. A designates the case of my improved cyclometer, this case being preferably of the shape shown in the drawings and having the side or rim a over which fits a lid or cap A. This lid or cap A is preferably held in place by means of lugs a extendinginwardly there from at its ends and provided with holes to receive the set-screws a The bottom or lid A of the casing is preferably formed with a sight-opening covered by a glass plate A to permit the inspection of the figures arranged upon the side of the gear-wheels immediately above it. By the removal of the lid A ready access can be had to the mechanism within the casing A in order to clean or repair the same or to reset the wheels. To the outside of the lid or cover A is preferably connected a boss B formed with a longitudinal slit or opening Z) and with a transverse seat or perforation to receive the arm 0 of the bracket C, whereby the eyclometer is held in position upon the machine. A set-screw (Z passing through a threaded hole in the boss B enables the sections of the boss to be clamped onto the arm 0 in order to retain the casing A in proper position. The bracket C is provided with'spring-metal arms C perforated to receive athrough-bolt D, whereby the arms will be securely fastened to one of the front forks of the machine-frame, as will be readily understood by those familiar with this class of devices.

In the side walla of the casing A are journaled the ends of a worm-shaft E, (see Fig. 3-,) this shaft being preferably formed of sections united together to permit the shaft to be readily set in place. Preferably the main section of the shaft E will be formed with a head 6, perforated to receive the inner end of the shorter or outer section of the shaft, these sections being joined together by a pin a. To the outer end of the shaft E is connected the sprocket or spur wheel E, that receives motion from a suitable striker-pin, (not shown,) attached to the Wheel of the machine in manner well understood. Preferably the reduced portion of the inner section of the shaft E is encircled by coil-spring f, that bears upon the side of the casing adjacent the end of the shaft and so guards the shaft against accidental rotation. VVith the screw-threaded portion or worm E of the shaft E engage the teeth of a gear-wheel G, with which is con nected a dial H, whereby each individual mile or fractions thereof will be registered. By preference the connection between the gearwheel G and the dial II is effected as shown more particularly in Fig. 7 of the drawings-- that is to say, the gear-wheel G is formed with a hub 9 having a reduced portion that projects upwardly through the top plate of the casing A, this hub being interiorly threaded to receive a correspondingly-threaded stem or bushing vi, the .llanged head t" of which rests upon the upper end of the hub g of the gear-wheel G. l; y this means the gear-wheel G can be accurately held in position without danger of unnecessary 'i'riction. The dial II is attached to the bushing i by means of a serewj, that passes through the dial and enters a threaded hole formed in the bushing i. By preference also a washer 2 is interposed between the under side of the dial II and the headed end 2" of the bushing 17, and a similar washer-3 rests upon, the upper face of the dial ii, and upon this upper washer is placed a plate 4-, preferably of spring metal, the arms 5 of which plate bear upon the washer 3 and thus hold the dial with sufficient force to prevent its accidental turning and insure its movement with the bushing 1 as the latter revolved by the operation of the gear-wheel (i. To prevent the binding of the dial, I pre- 'ler also to ti t a short sleeve (3 around the screw j, this sleeve serving to take the pr when the screw is forced in ward very ti htly. The sleeve 6 sets within an. opening formed centrally oi the dial ll.

At the opposite end of the casing A are mounted the ratchet-wheels M and N, arranged in the same horizontal plane as the gear-wheel G and upon the opposite side of the worm-shaft E. The ratchet-wheel M is preferably formed with a hub in that extends upwardly through the ratchet-wheel N and through the top plate of the casing A, and this hub in is formed with a threaded opening to receive the correspondingly-threaded bushing 0, the expanded cap or head 0 of which bears upon the upper end ot the hub HI outside the casing A. Upon the end 0 oi the bush ing 0 rests the dial i that is held in place by means of a screw p, the threaded end oi which passes into a correspondiiigly-threaded hole formed in the bushing (i). Preferably a washer 7 and friction-plate 8 are interposed between the head of the screw 1) and the dial 1, and by preference also a short sleeve 9 encircles the screw p and serves to receive the thrust of the screw-head when the screwp is screwed tightly to place. The ratchet-wheel N fits loosely upon the hub m ot the ratchet-wheel M, and above this ratchetwheelh and loosely encircling the hub m is the spring plate or washer 12, the upturned outer ends of which bear upon the under side of the top plate of the casing A. The outer face of the ratchetwheel M. near its periphery is marked with a series 0t figures indicating miles up to one hundred and the lower face of the ratchetwheel N is marked with figures and points indicating hundreds of miles up to ten thousand, and in order to permit the figures and points upon the ratchet-wheel N to be readily seen the ratchet-wheel M will be termed with a segmental slot or sight-opening in opposite that part of the ratchet-wheel N upon which the figures and points are marked.

In order to transmit motion from the gearwheel G,which For convenience m ay be termed the traction-wheel, to the ratchet-wheels M and N, which for convenience may be termed the totalizing-wheels, I employ the mechanism next to be described. Upon the upper face of the gear-wheel G adjacent its hub g is fixed an eccentric-pin and around this pin and the hub 9 his the yoke-shaped end of the drivingarm R, the opposite end ot' this arm R being formed wit-h a long slot or opening 2" that loosely receives the hub m of the ratchet-wheel. M, the driving-arm 11- located immediately beneath the top plate ol the casing. The driving-arm R is provided with a pawl R arranged to engage the peripheral teeth of the ratchet-wheels M and \Vith the teeth of these ratchet-wheels also engages a check-pawl S that is pivotallyeonnected to the casing, as at 5', this check-pawl beingforeed into normal engagement with the teeth of the ratchet-wheels by means oi a spring .9.

From the foregoing description it will be seen that when motion is transmitted trom the machine-wheel to the sprocket or spur wheel E and to the worm-shaft E the gearwheel G will be revolved and like revolution will be thus imparted to the indicator-dial .ll attached to the hub of this wheel. its the gear-wheel G is thus revolved. the eccentricpin will transmit a back and forth and swinging movement to the driving-arm 1?, thereby causing the pawl R of this arm to revolve the ratchet-wheels All and N. The periphery of the ratelietwlieel M is formed with ninety-nine teeth, while the eriphe1 v of the ratchet-wheel N is termed with one hundred teeththat is to say, there is a ditierenee of one in the number of teeth with which these wheels are provided. Consequently while the wheels M. and N are revolved by the driving-arm R and its pawl It, it will be seen that at each complete revolution of these wheels the ratchet-wheel N will lllitliO a slight additional movement beyond the movement of the wheel M, and this lllOYt ment will. equal the space between the points In arked. upon the face of the wheel N. ll'enre it will be seen that at each complete revolu tion of the wheel ll, which will indicate a hundred miles, the relative position between the wheels M and N will be shifted the dis tance of one point upon the wheel N and this point will indicate upon this wheel the distance of one hundred miles traveled by the machine. The ratchet-wheels M and N thus totalize the number elf miles traversed by the machine until such number reaches ten thousand. Upon the inside of the casing A a pointer T projecting from pawl S extimds slightly over the ratchet-wheel M, enabling the extent of revolution made by this rat rhetwheel to be readily noted.

The dials ll and P are furnished respectively with. a pin or projection 72 and located at the zero-points of the dials, and to the top plate of the casing is fixed a bar Y carrying the pointers r and 1" that project,

respectively, above the dials II and P. The dial II has its upper face marked with a series of points and figures indicating the frac tions of one mile, while the dial P has its face marked with a series of points and figures indicating miles up to one hundred.

At the beginning of a ride the dials will be turned until the projections 7t and p are brought beneath the pointers o and o, the projections h and p permitting the dials to be readily shifted. It will be understood, of course, that this shifting of the dials will in no wise disturb the fraction-wheel G or the totalizing-wheels M and N, since the dials are frictionally connected with their respective wheels. The exposed faces of the dials will permit the rider to readily observe the distance traveled, while by inspecting the totalizing-wheels through the glass A upon the under side of the casing the total number of miles traveled beyond one hundred and up to ten thousand can be readily noted.

By arranging the fraction-wheel and the totalizing-wheels in the same horizontal plane and at opposite sides of the worm-shaft E, I am enabled to use a very shallow casing, and by the driving mechanism shown the movement is readily and effectively transmitted from the fraction-wheel to the totalizingwheels. By attaching the dials to their respective wheels in the manner above described these dials can be readily shifted when desired, and all unnecessary friction incident to the rotation of the wheels and dials can. be avoided.

It is manifest that, instead of employing revolving dials, revolving pointers might be used, and other changes within the knowledge of the skilled mechanic may be made without departing from the spirit of the invention. So, also, any equivalent means may be used for the spur or sprocket wheel E, and I do not wish the claims to be limited specifically to a construction embodying such wheel.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is
